Translation of the abstract (English)

The paper examines the effects of international migration on the host country using a theoretical model.

In chapter one, the term migration is explained. Then in chapter two, after a review of the most important models about migration, the union bargaining model is introduced and extended with the possibility of international migration to analyse the effects of immigration.

Chapter three shows in detail the experiences of the Federal Republic of Germany with immigration since its foundation, including the effects on dempography, labour market, aggregated demand, public budget and on the society.

In Chapter four the enlargement of the European Union towards the East and the freedom of movement within the new EU-25 are described. Forecasts about the expected migration are presented as well as criticism on such forecasts. Effects on the social insurance system and on the old and new member states follow.
